Vilebrequin is a French YouTube channel focused on cars, challenges and experiments, created by presenters Pierre Chabrier and Sylvain Levy. The phrase c'est parti is a common French expression meaning let's go, and it is often used in their videos as a signal that an experiment, race or stunt is about to begin. Short clips of the catchphrase have circulated among fans and editors as a quick way to open a video with the same playful, high-energy tone. It remains useful because it is instantly recognisable to French-speaking viewers and easy to understand as a starting cue even without translation.
